' a. citizen. of the United States, residing at end view {)Il' the paperfeed roll.

, desk l-xn Francisco, in the county of San Fran euro and State ofCali'fminia, have invent ed a new and useful Sanitary Guard forTelephones, of which the following is a specification in such full andclear terms as will enable those skilled in the art to construct and usethe This invention relates to a sanitary device for telephone mouthpieces. Its ohject is to provide means whereby the mouthpiece ot' thetelephone will he kept from accumulating disease germs from the sputumof telephone users.

Another oh yeet of the invention is to provide means whereby theprotective covering of the mouthpiece will be ,automatically sh'i'l awhen the telephone user picks up the telephone.

Other objects wil appear as the descrip tion proceeds.

resents the sending apparatus of the telephone on which is secured thisattachment.

The numeral 5 represents a plate which is secured to the telephonesending apparatus by screwing the mouthpiece intothe usual positionthrough said plate. The plate 5 is provided with forwardly projectlugflanges 6 at each side thereof, which flanges support the paper roll andthcapparatus for shifting the paper used to'prevent soiling themouthpiece. Projecting forwardly from the top and bottom of the plate 5are two skeleton frames 7 and 8, each of which serves toguide and holdthe paper in the .proper position in front of the mouthpiece. The upperguide 7 is pro vided with upwardly projecting ears 9 roll 10. At theupper end of each of the set of flanges (3 there is an opening in whicha rod 11 is inserted, said rod carrying a spring 15 which bears upon apresser plate 13, said presser plate bearing in turn upon the paper rollto regulate the tension of the paper as it is pulled across themouthpiece. This presser plate has two backwardly extending ears througheach of which passes the rod carrying the spring; 15.

Atthe lower portion of the flanges 6 there is a paper teed roll 16. Thispaper feed roll is loosely journaled upon a shaft 17 said shalt having aratchet wheel 18 atoms end and a small pinion 1.9 at the other end. Thepaper feeding roll has a pawl 20 which bears upon the ratchet pinion, aspring 21 holding said pawl in engagement with said ratchet pinion, thuspreventingthe paper feeding roll from moving in one direction. Above thepaper feeding roll there is a shaft 22 having a pinion 23 thereon, saidpinion 23 being in mesh with the small pinion on the shaft of the paperfeed roll. The large pinion is provided with a pin 23* which projectsthrough a. slotin an operatcars 30 through each of which the said shaftthe used strip of paper.

The standard of the telephone has at-tube 33 surrounding the same saidtube'being made in two parts for the purpose of readily placing the sameupon the telephone standard, and it is. provided with a slot 34 toprevent the same from twisting around the standard, said slotmovingalong the receiver arm when the standard is picked up. .axtendingfrom the top of the sleeve is a link 35 which link connects with therearwardly extending arm of the operatin shaft and enables the paperfeed roll to be moved'such an amount as may be necessary each time thetelephone is lifted up.

Where it is desired to use a wall telephone instead of a portabletelephone the operating shaft is turned downwardly so that it is inconvenient reach of the telephone user as shown at 36, thus enabling thepaper to be fed across the mouthpiece should the telephone be one of theso called "Wall.telephones or should it be desired to operate withoutthe automatic feature.

The operation of the device is as follows The paper supply roll isplaced upon the upwardly projecting ears at the top of the device, thepresscr plate bearing thereon. The paper is then pulled across themouthpiece, over the guides and is inserted between the-roller and thepresser plate hearing thereon. The device isthus ready for use and eachtime the telephone is picked up the sleeve thereon will lift theoperating -arm and cause a certain amount of paper to be pulled acrossthe mouthpiece, thus presenting a fresh piece of paper for the telephoneuser.

Having thus described my invention what I claim as new and desiretosecure by Letters Patent of the United States, is as follows 1. Asanitary deviize for telephones comprising a frame adapted to be securedto the sending apparatus of a telephone, a paper roll, means tosupportsaid paper roll on said frame, guides to hold said paper in frontof the, mouthpiece of a telephone, a paper feed roll jonrnafled in saidframe, and means to cause said feed roll to pull a predeterminedquantity of paper across said plephonemouthpiece when the" telephone islifted up, substantially as described.
